Black.

I wear a lot of black. If you open my wardrobe you will pretty much see black and more black. It is such a comfortable colour to wear, and always looks neat and timeless. Here's what Christian Dior wrote about black in 'The Little Dictionary of Fashion':

The most popular and the most convenient and the most elegant of all colours. And I say colour on purpose, because black may be sometimes just as striking as a colour.

It is the most slimming of all colours and, unless you have a bad complexion, it is one of the most flattering.

You can wear black at any time. You can wear it at any age. You may wear it for almost any occasion. A 'little black frock' is essential to a woman's wardrobe.

I could write a book about black...
